Title: Active-type distance measuring apparatus
Inventor: KAWAI TORU
IPC: G01C3/06
Filed: 1984-11-08
Abstract: PURPOSE:To measure a distance effectively free from waste of energy, by controlling an output of a light projector of an active-type distance measuring apparatus corresponding to the focal length of a photographing lens. CONSTITUTION:When an infrared beam is projected from a luminous element 1, a light-emitting lens 2 develops a spot image on a specimen 3 and at the same time, the dispersed and reflected spot image develops a spot image on a sensor 5 by a light-receiving lens 4. A signal corresponding to an output difference generated in parts 5-1, 5-2 of the sensor 5 drives a motor 9 by an output from a focus point detecting circuit 7 to allow a focusing lens 20 to travel in the direction of the optical axis and further, allows the sensor to travel up and down through a jointing member 3, repeating these travels until the output difference dies out. When the specimen is moved comparatively too far to get a beam of reflected light returned, a signal advising unavailability of the measurement is issued, a comparison of hyper focal length signal corresponding to a focal length signal and photographing distance signal by the position of a focusing lens is made by a comparing circuit 12 and a lens 20 is displaced until both signals are brought to coincidence.

Title: Method for laminating thermoplastic film or sheet
Inventor: TOSHIMA KOZABURO
IPC: B32B37/06
Filed: 1987-09-18
Abstract: PURPOSE:To heighten adhesion between laminating sheets and consequently prevent ply separation from occurring by a method wherein one surface of a sheet is coated with solventless polyurethane-based adhesive so as to be fixed under heat and pressure to another sheet or film and, after that, to be aged as a whole under hot state. CONSTITUTION:One surface of an air permeable sheet or a finely porous thermoplastic resin film or sheet is coated with solventless polyurethane-based adhesive by the thickness of 0.5-1.5mum so as to be fixed under heat and pressure to another sheet or film and, after that, to be aged as whole under hot state. If the thickness of the adhesive is more than 1.5mum, the air permeability of the adhesive layer is lost. If that thickness is less than 0.5mum, enough adhesion is not realized. When the aging is done normally for 36-60 hours at 35-40 deg.C after the fixing of the sheet under heat and pressure, the adhesive fully solidifies, resulting in preventing ply separation from occurring.
